Hadong Budaebuin

Grand Internal Princess Consort Hadong (23 September 1522 – 24 June 1567), of the Hadong Jeong clan, was a Korean Joseon dynasty royal family member through her marriage with Grand Internal Prince Deokheung, the son of Jungjong of Joseon and Royal Consort Chang of Ansan Ahn clan. She was the biological mother of Seonjo of Joseon who died not long before he ascended the throne.

She was also known as Princess Consort Hadong (하동부부인, 河東府夫人), Princess Consort Hadong (하동군부인, 河東郡夫人) or simply Lady Hadong (하동부인, 河東夫人) before eventually became Budaebuin.

Early life
The future Grand Internal Princess Consort Hadong was born into the Hadong Jeong clan on 23 September 1522 as the daughter of Jeong Se-Ho, and his wife, Lady Yi of the Gwangju Yi clan.

Her father, Jeong Se-Ho was the son of Jeong Sang-Jo and Lady Ahn of the Juksan Ahn clan; making him the grandson and Lady Jeong a great-granddaughter of Jeong In-ji. Her paternal grandmother, Lady Ahn, was the granddaughter of Princess Jeongui; who was the second daughter of Queen Soheon and King Sejong. Thus making her the maternal great-great-granddaughter through her grandmother.

Meanwhile, her mother was the daughter of Yi Se-geol and Lady Jeon of the Jeongseon Jeon clan. Lady Jeong had 2 older brothers and a younger brother. Her paternal cousin, Lady Jeong of the Hadong Jeong clan, eventually became the grandmother of Queen Yu, the wife of King Gwanghaegun.

Marriage and later life
She later married Yi Cho when he was still Prince Deokheung and was honoured as Princess Consort Hadong. Her father was then honored as Duke Hyogan, Internal Prince Hadong.

During her marriage, she gave birth to a son in 1545, a second son in 1546, a daughter in 1548, and a third son in 1552.

On 24 June 1567, during King Myeongjong’s 22nd year of reign, she died at 46 years old. Her tomb is located near from her husband's tomb.

Seonjo's ascension to the throne
Two months after her death, her third son, Yi Yeon, Prince Haseong succeeded Myeongjong who died without a royal heir. Thus becoming Myeongjong's adopted son when the prince ascended the throne as the 14th king of Joseon. Her husband couldn’t be King because of his low background, so the throne was immediately passed down to his legitimate son. On 1 November 1569, as the Princess Consort was the biological parent of the reigning King, she was granted the royal title of Princess Consort Hadong at first, but was later changed to Grand Internal Princess Consort Hadong.
